My machine comprises, in the main, two

parts,a 'ran'iework or carriagel and an inner frame or ljattorm 2 upon which is mounted an electric motor 3, the abrasive drum 4. 4the gearing; between them and the exhaust fan 5 "by means of wh'eli the dust from the abrasive wheel may be lifted and collected into a suitable dustcollecting bae- 6, preferably hungI on the carriage vl at the rear of the machine.

The outer `framework or carriage l'preferably comprises tour vertical `and corner columns or posts 7, S, 9 and'lO, the columns? and 8 being preferably at the rear end' of the ii'iachiiie and the coluinns'9and l() at the front end of the machine. Theposts orcolumns 8 and 9 are preferably `connected by a web or bar 1l. near the lower end of the said posts and at their top ends by a crossbar 12, which 'TIE l may be somewhatarclied, as showii in Fig. 1.

On the other side of the machine, the columns and 7 are similarly connectedftogetherby a web or bar 13 near their bottom ends and their top ends are connected ,byI a similar crossbar 14. The posts or columns 7 and 8 are also connected near their bottom ends by a crossbar 15 and near theirupper ends by aeressbar 165 sadfbere y.15. and 16, being conneCtedto-and Supporting vertical guide web l-Zthe inner ,Surface of which s preferably smooth andy which,belowv the plane of. the, motor 3, is provided with a vertically elongatediguideway or slot 18, On the o p- Pesite erfreut eideof-fthemeehne,the earriage isl similarly provided with a. similar lowercrossbar: 19, a similar .upper crossbar and a verticalguide web21 having. asimilar vertically disposed elongated slot 22 in horizontallalinement with the guideway or Slot/18am the .vertiCelwebA 17..

The inner frame 2compri`ses a .substantially rectangular; platform 29, having a plane upper surface `on which is mounted and supported the electric lmotor Projecting downwardly from the underside of the platform 29 are two parallel vwebs, 3Q and 31 connected atitheir lower ends by a sleeve 32 proyvidingt a bearing for a shaft 33 upon one end of which the abrasive roller or drum 4 is rigidly mounted. On the rear` and front sides ofthe platform 29 and forming a rigid part thereof are guide plates 34 and 35`having yparallel vertical faces adapted respectivelyto bear smoothly against and slide upon the smooth, inner sidesl of the vertical guide websgl( and 21, respectively. and from the substantial lcenter oflthese guide plates out-V wardly project trunnions 36 and 37 respectivelyslidingly fitted within the guideway.

hfounted 'n lined beari, gs38, and 39"re'I `lspectively on' the vertical guide webs 17 andy 21 respectively, is" a` cam shaft 40 provided at its,endsrespectively with two cams 41 and 42 extendingwlaterally under the trunnions 36 and 37 respectively and this shaft 40 is also providedwitha lever 43 rigidly secured to the vshaft an'deXtending outwardly therefrom vided with a handle 43rigidly secured thereto l and preferably extending upwardly just outside ofthe post or column 8 soy as to be available for convenient manipulation of the right hand-,of the operator of the machine. llhis handle or lever-48 may bepro'videdV with a pawl 49 operable by abutton 5() at the top the lever. to raise and lower the pawl 49 Vwith respect to a segment 51 projecting forwardly p from 4the post or column close to the handle or lever 48 and provided Awith ya suitable l notchl 52 adapted to be engaged by the pawl 49 when the lever is drawn rearwardly to substantiallya vertical position. -`For the purpose efv makina Clear .the rUrPOSe and v,Opereytion ofthisl mechanism and referring to Figs.

1 and 3, and assumingl the parts to `be in the position shown in wFig. 1, Ijfwill here state that when the lever or handle `43 is pulled rearwardly l to substantially a'vertical position, theypawl 48llwill fall into the notch 52 of the segment and willbe operative to hold the lever in that position when the handl of the operator is removed therefrom. In so yturning to this position, the shaft 4G will be rotated, raising the free lend ofthe cam 47 in engagement with the underside of the lever 43 thus turning the shaft'40 and with it the cams 41 and 42 respectively beneath the trunnions 36 and 37 andlifting the said trunnions 36 and 37and with them the platform 23 and the parts carried thereby, and consequently lifting the abrasive roller or drum 4 upwardly out of contact ywith the floor to an inoperative position. To lower the drum to the fioor the operator dra-ws slightly rearwardly Von the handle vor lever 4S, depresses the button `50 which lifts the pawl 49 out of the notch 52 and permits the operator thenV to allowthelever or handle `43 to swing forwardly under the weight of the parts supported von the cams-41 and 42V until. the'abra- "sive roller 4 shall lagain make Contact with the floor.

The motor 3 is preferably provided with a 'driving wheel Y53 which is illustrated vas a' lill' abrasive roller over the floor. p 'of the abrasive roller upon theiioor will be sprocket wheel cooperating with a sprocket chain 54 which passes Varound the underside of a sprocket wheel 55 rigidly mounted on the shaft 33 to drive the saine. The outer end of the shaft 33, on the right hand side of the machine, is provided with the aliirasive roller or drum 4 rigidly secured thereto so that this roller 4 is driven from the motor 3 through the sprockets and 55 and sprocket chain 54 to abrade or finish the floor. The opposite end of the shaft 33 is provided with a pulley 56 connected by a belt 57 with a pulley 58 on a .fan shaft 59, one end of which may be journaled in a hearing (S in the web 3l and the other end or' whieh is suitably journal-ed in the casing of the fan 6l. which is preferably mounted and secured to the inner side oi' the web 30.

The exhaust tan 6l may be ot any approved type wherein, by the rapid rotation of the blades, air is drawn into the center oi' the l'an and expelled centrilugally from point tangentially to the outer ends ot the Yian blades. `Such. an exhaust ian 6l is shown `in Figs.` l and 2 and the yopening at the center thereoffisin registration with an opening 62 through the web 30. On the opposite side of the web is secured a pipe or conduit 63 which extends outi Hardly between the vertical courses o'f the sprocket chain 54 and then curves downwardly and -to the rear terminating in a hood or head 64 close to the rea sidev of the abrasive wheel4 and .extending down close to the ioor. From the discharge opening 65 of the Jfan 6l extends a :fiexible conduit GGeXtending vertically up to and over the upper cross bar 16 and then downwardly where it is attached to the upper end of a dust collecting bag in any operative manner.

lVith the parts abraV ed and disposed in the manner above described it will be apparent that when the lever or. handle 48 is in the position shownin Fig'. l, the entire weight of the motor 3, the inner-iframe 53 and the parts carried thereby, ineludin the abrasive drum 4, the gearing between it and the motor, the fan and'its connections will all be supported on the floor while only the w the outer traine or carriage.y a relatively small fraction oit the weight of the entire meehanism, will be supported on the rollers and the castor Q The pushing ot the carriage l forwardlyV and baokwardly will move the The pressure more than sufficient to thoroughly Vfinish the floor. l

l counterbalaneed` so that the operator may vary and Aadjust the pressure between Vthe abrasive roller and the iioor for different operations and conditions. To this end I preferably provide the shaft 46 adjacent the journal 44 with an arm or lever 67, the Aouter end of which is preferably provided with a fork 68. This lever is preferably rigidly secured to the shaft 46 to rotate therewith. Passing` through or between the arins of the fork 68 I provide va serewthreaded stud 69 which may be rigidly secured to the post or column 7 in any suitable manner to project horizontally `forwardly there from, Over the free end of the screw or stud 49 threaded a hand wheel or nut 70 between which and the fork and around the screw or stud is a spiral compression spring. When the hand lever 48 is released so las to permit the abrasive roller or drum 4 to rest on the floor, the free end of the forked arm or lever 67 will bear against tiicradjaeent end of the spiral .spring 7l and compress it between the free end of the lever and the hand wheel. By vadjusting the position or' the-nut or hand wheel 70 on the screw any desired part of the weight of the inner traine 2 and the parts carried thereby may be balanced or counterbalanced by the spring 7l, and the abrasive drumnxay be made to bear on the floor with any desired pressure up to that produced by the entire weightot the inner frame and parts carried thereby.

It is to be observed that the platform 29 is supported on the cams 4l and 42 by the trunnions and 37 resting thereon and that the guide plates 34 and 35 steady the platforni between the guide webs 17 and 21 but there is nothing in the construction heretofore described to prevent its platform and the parts carried thereby'irom rotating on the trunnions 36 and37 as an axis so that when looking toward thev machine from the rear thereof as in Fig. 2, the entire inner traine might rotate about the trunnions 36 and''lT and swing the abrasive roller or drinn 4 upwardy from the floor. That would, of course, be contrary to the desired purpose, operation, and function of the device. I therefore provide an adjustable connection 72 between the motor 3 and the outer traine l, comprising a vserewthreaded rod 73 hingedlyconnected'to the motor casing to swing on a `horizontal axis about said pivot and an alined stud rod 74 similarly hingedly cony nected to a lug or projection 75 on the pillar or post 9 as shown in Fig. l and having a turnbuekle 76 vswiveled thereon, threaded over the rod 7 S, and clamped in any desired position by a jamb nut 77..- Thus by vturning the turnbuclile 76. the whole inner rame and the parts carried thereby, may be swung Vabout thehorizontal axis of' the trunnions to bring` the operative portion of the abrasive vroller 4 parallel to the floor to be finished thereby. This adjustment 72 also provides a means whereby the abrasive roller 4 may be tilted slightly in a plane normal to 'the floor and coincident with the axis of the abrasive roller when there are portions of the floor which are not strictly in a horizontal plane andv which if the device were not so adjusted would be grooved by the outer edge of the abrasive roller when the machine is passed over such an uneven surface or slightly inclined surface.

In orderto hold the trunnions 86 and 87 at all times vfirmly against the upper surfaces of the cams l1 and 42 during the operation of the device7 and particularly when a part of thev weight of the inner frame and the parts carried thereby are counteibalanced or partially balanced by the spiral compression vsprinpl 71, I preferably provide each of the triiniiioius with a saddle 78, the underside of which rests upon the trunnions and the upper side of which is provided with a lug 79 which projects upwardly into the lower end of a coiled spring 80. The upper end of the spring fits over a lug 81 of a circular cap 82 rotatably fitting against the lower end of an adjusting;l screw 88 'iassiiig through a hori- Zontal web 84- on the face of the vertical guide webs 17 and 2lrcspectively. By'adjusting Vthe position of the screw 88, the spring between it and the saddle 78 may be compressed to hold the trunnions iixedly but yieldingly against the upper surfaces of the lifting` cams 41 and 42. I

-In Vorder that the sandpaper or abrasive clothV may be 'wrapped around the drum l and held there firmly duringr the operation of the device, I providethe drum l with a mechanism shown particularly in F l, 5 and 6.

The drum 4L preferably provided with anA undercut channel 85 in the circular face thereof, providing a space within `w'iicli may be mounted a pair of brackets 86 in each of which are journaled two rollers y87 and 88. The cylindr'cal heads 89of the brackets 86 are preferably slightly, smaller in diameter than `the rollers 87 and'88, The brackets 86 may be securely bolted tothe :tlat bottom of the undercut channel 85.` Between the pair of brackets in which a roller 86 or 87 is mounted, the diameter of the roller is slightly larger than the diameter of the heads of the bracket. At the ends 90 of this central portion, the diameter of the rollers is reduced to fit the `i'ournal openings in the heat s of the bracket. Outside of the brackets the reduced diameter of the rollei;l 87 is preferablyV provided on one side with a Lgear 91 having' a hub 92 of the same diameter as the roller 87 and rigidly secured tl creto in any suitable manner, as by a set screw 98. The other end of the roller 87 is provided with a ratchet 9i instead of being provided with a `gear 91. This ratchet 94 may be secured totherediiced end of the roller 87 by a set screw 95. VPivoted upon the bracket V86 adjacent the ratchet 94 Abetween the rollers.

is a pawl 96, the free end of which is yieldably held against the surface of the ratchet by a spring; 97. The roller 87 is preferably provided with a flat surface 98 as is also the hub 92 of the gear 91, and the heads 89 of the brackets 86 are similarly provided witha flattened portion 98 disposed in a vertical or radial plane. l

The roller 88 is likecthe roller 87 except that the ratchet 9i may be omitted and replaced by a sleeve 99 on one end of the same general diameter as thatrof the rollers 87 or 88 and secured thereto by a set screw 100 and the other end of the roller 88 is provided with a gear wheel 101 to mesh with the gear 91 and with a roller hub 102 secured to the reduced end of the shaft by a set screw 108. The roller 88, including the sleeve 99 and the hub 101 are provided with the same kind of a flat surface 98 extending longitudinally thereof, as are the corresponding parts of the roller 87 and the heads 89 in which the Vroller 88 is journaled are also similarly provided with like flat surfaces 98 but disposed in a vertical or radialv planeparallel to the correspondingl surfacesin the heads in which the roller 87 is journaled.

To secure the sheet of abrasive paper 1.04 to the drum 4l, the sheet of paper of the width of the drum is `wrapped around it and the ends are tucked in between the rollers 87 and 88 while the flattened portions 98 of the two rollers are parallel and substantially coincident with the flat surface on the heads 89.

The outer end of the roller 87 may be pro vided with a polygonal hole 105 as shown in Fig. 1. lVhen a wrench, having an end theV cross-section of which :tits into the hole 105, is inserted therein, the roller 87 may be given a turn in a clockwise direction (as viewed from the position shown in Fig. et) and that quickly brings the circular portion of the rollers 87 and 88, including' the sleeve 99 and of the hubs 92 and 102 closer to each other in the planes of the axes of the rollers than the thickness of the paper inserted therebetween, whereupon the paper will be pinched Slieetsinivardly, applying a longitudinal tension to the sheet 104i of abrasive until it is.

drawn tight and smoothly against the outer surfaceof the drum el. When the paper lhas A 911- and consequently the rollers 87 and 88y from rotating` backward and releasing the paper 101i` until it is desired to substitute a new abrasive surface. l

If desired, each roller may be provided with a wrench hole '105 for since the two rollers 87 and 88 are geared together at their vinnerendsthey will be rotated'together by Now a further rotationof the rollers 87 and 88 draws the ends of the turning either. Such slight variations in details are fully within the aim and scope of my invention. v

Having thus described my invention, what I claim and desire to protect ,by Letters Patent of the United ,States is: y
